The Golden Globes ceremony is a night when Hollywood stars shine their brightest. At the recent red-carpet event, leading man Viggo Mortensen had plenty to smile about: Green Book, the movie in which he co-starred, picked up the award for Best Motion Picture—Musical or Comedy. But fans looking at the veteran actor's big smile today might not realize that it once looked very different. A few years ago, an accident during the filming of The Two Towers took a major chip out of Mortensen's front tooth!
That might be OK for some movies (think The Hangover or Dumb and Dumber)—but it's not so great for everyday life. Fortunately, Mortensen visited a dentist promptly, and now his smile is picture-perfect. How was that accomplished? He didn't say…but generally, the best treatment for a chipped tooth depends on how much of the tooth's structure is missing.
If the tooth has only a small chip or crack, it's often possible to restore it via cosmetic bonding. This procedure can be done right in the dental office, frequently in a single visit. Here's how it works: First the tooth is cleaned and prepared, and then a tooth-colored resin is applied to the area being restored. After it is cured (hardened) with a special light, additional layers may be applied to build up the missing structure. When properly cared for, a tooth restored this way can look good for several years.
For a longer-lasting restoration, veneers may be recommended. These are wafer-thin shells made of durable material (most often porcelain) that cover the front (visible) surfaces of teeth. Strong and lifelike, veneers can match the exact color of your natural teeth—or give you the bright, high-wattage smile you've always wanted. No wonder they're so popular in Hollywood! Because veneers are custom-made for you, getting them may require several office visits.
If a chip or crack extends to the inner pulp of the tooth, a root canal procedure will be needed to keep the tooth from becoming infected—a situation that could have serious consequences. But you shouldn't fear a root canal! The procedure generally causes no more discomfort than filling a cavity (though it takes a little longer), and it can help save teeth that would otherwise be lost. After a root canal, a crown (cap) is generally needed to restore the visible part of the tooth.
When a damaged tooth can't be restored, it needs to be extracted (removed) and replaced. Today's best option for tooth replacement is a dental implant—a small, screw-shaped post inserted into the bone of your jaw that anchors a lifelike, fully functional crown. Implants require very little special care and can look great for many years, making them a top choice for tooth replacement

Your teeth naturally wear as you age, but you may be making it worse if you grind your teeth.
Teeth grinding is a behavior that causes the teeth to gnash, grind or clench against each other generating forces greater than those produced from normal biting. These forces often result in tooth wear that cause not only functional problems but result in a more aged appearance. Grinding occurs while a person is awake, but most often episodes occur while asleep at night.
Teeth grinding is quite common in children, but not usually of great concern since most grow out of it. There's even a school of thought that teeth grinding might even help readjust an uneven bite.
Among adults, though, other factors seem to contribute to teeth grinding. Many researchers believe nighttime grinding occurs as a person passes through different sleep phases including deep REM (Rapid Eye Movement) sleep. It may also have a connection with chronic snoring.
Certain medications seem to contribute to teeth grinding, particularly psychoactive drugs like amphetamines. Nicotine falls in this category, which could be why tobacco users report twice the incidence of the habit compared to non-users. Teeth grinding is also connected to another fact of modern life: stress. People who grind their teeth tend to have higher levels of anxiety, hostility or depression.
Because there are multiple triggers, there are many treatment approaches. Whatever course we take, our aim is to eliminate or minimize those factors that contribute to your habit. For example, we can create a custom mouth guard for night wear to prevent the teeth from making solid contact and thus reduce the biting pressure.
Perhaps the most important thing is to control or reduce stress. This is particularly helpful at night to prepare you for restful sleep by changing some of your behaviors. We also encourage investigating other stress therapies like biofeedback, meditation or group therapy.
Whatever the means, bringing teeth grinding under control not only reduces problems now, but could also help prevent abnormal teeth wearing and future health issues down the road.

In the realm of restorative dentistry, dental implants are king. A dental implant can replace a tooth with a permanent, life-like restoration with a solid reputation for durability.
Implants are also known for one other quality — variety. Not all implants are alike, and they have varied applications for use. Available in various shapes and sizes, they can be used for a single tooth or as part of a multiple tooth bridge or overdenture. And while their basic architecture is the same, you also have two options for how the permanent crown (the visible tooth portion) attaches to the implant: screwed or cemented.
A screw attachment can securely fasten a crown to an implant without the need for cement; it also allows for easy removal for repair or replacement should the crown become damaged or worn. On the other hand, it could pose a cosmetic problem — even though the access hole for the screw may be covered with a tooth-colored filling, it could still be distinguishable from the rest of the crown. There’s also a slight risk of the crown chipping around the access hole.
A crown cemented to the implant won’t have this cosmetic issue with an access hole, and will look just like a natural tooth. But unlike a screwed crown, removing a cemented crown can be more difficult. The cement may also cause gum inflammation and potential bone loss in sensitive patients.
The condition of your mouth, the type of implant you’re receiving and other circumstances will all factor into determining which method is best for you. If we’re “immediately loading” the crown (meaning we’re affixing a temporary crown to the implant immediately after placement in the jaw), then the screw method may be more advantageous. Aesthetically speaking, though, a cemented crown may be a better option in terms of final smile appearance.
But whichever method is used, you’ll still benefit from what implants do best — help you regain the function lost from a missing tooth and change your smile for the better.
